Can anyone tell me what kind of crusher/grinder one needs to make their own
grog?



Thank you.

Dear Tony;

I use Crush 'n Mill that used to be manufactured in Portland, OR for
gold miners. It is a Jaw Mill, that is, a fixed plate has a moving and
sliding down plate that progressively mills the material to the final
dimension of the separation between the plates. It is powered by a
five-horse Briggs and Stratton. Works a charm for most anything if it
its not too soft....... hard things don't gum up the jaws.

If I need plasticity, I ball Mill further.

Check used equipment for the mining industry for good leads on a
hammer, or jaw mill.

Best, Hank in Eugene
ps: the miner and the well driller should be our friends.

Hello Tony,

A friend is going to help me build a small jaw crusher one of these
days. It will crush down to 6-minus mesh or something.

I've used a mining lab in Reno to crush materials for me. They use a
cone crusher, and I screen the stuff (feldspar) to size.

Or you could make one of Ivor's "Dolly Pots". It's a 4" steel pipe
welded onto a piece of flat plate steel, and the material is pounded
inside with a heavy iron bar. I really should build one of these, as the
old iron is probably out there in my metal pile.

There's a description of the Dolly Pot in "The Potters Alternative" by
Harry Davis. Also in this book are plans for a 'Roll Mill' that looks
like it would make dandy grog.

I pile up broken and unclaimed bisque pots in a parking spot in
front of ceramics, then each day I park on them.

This does two things; it saves me a parking space because no one
else will park there and it breaks down the clay into grog.

I am not looking for fine grog. The grog I am making is for
homemade castable refractories. I don't park the K1100 on the
grog pile.

A "hammer mill" is often used. The local refractory company use to make
their own grog but decided to stop about fifteen years ago because they
decided it was to noisy and dusty. They are located on the edge of an
industrial neighborhood near the ship channel.

A friend of mine uses a steel drum with a clamp-on lid with pieces of
heavy chain welded inside it, rotated at medium speed.

A "dolly-pot" is about the simplest crusher.
The simplest dolly-pot is a 2 litre steel coffee can as the mortar,
& a 1000 mm x 25 mm copper pipe jammed over
the ball of a hefty ball-peen hammer head as the pestle.

We have a Bluebird hammermill, and we use to grind up all our scrap bisque
into grog, but what a god-awful job, and what a high-maintenance machine.
We don't do this anymore. The hammermill sits there in the corner of the
claymixing room, waiting for extensive repairs. I will probably fix it
eventually, because it makes short work of grinding up scrap softbrick -
much easier on the machine than scrap grog. But it is essential to do this
outdoors, and when done the operator really needs to shed all their clothes
and wash them. It's hardly worth it with a hammermill.
Best wishes -

RAYMOND W GONZALEZ on tue 25 feb 03


In undergrad we used a machine that was thought to be used by the glass
program that had been terminated years before i got there. We thought it
was an appelate grinder as i recall, it was made by bluebird, and is
no longer produced. it had perforated steel screens that were of various
diameters. hammers spun and crushed the pots through the screen. it was a
great thing that i miss a lot.

When i moved here, to southern NM, i was taking a stroll through
UTEP's(University of Texas at El Paso) and they have the same thing. i have
seen several in my journeys. If you don't mind the LOUD noise, spitting
chunks of clay and immence dust (translation: wear ear, eye, and respiratory
protection) it is a great thing to have around the studio.

others may have refrenced this same machine under a different name. am i
incorrect in calling it an appelate grinder or in its origins?
